The link between cyclobenzaprine (Flexeril) administration and serotonin syndrome (SS) is subject to debate. Establishing such a connection is difficult because of the limited number of case reports available and the almost complete ignorance of its preclinical pharmacology. In this

The muscle-relaxing 5-HT(2) receptor antagonist cyclobenzaprine is structurally closely related to amitriptyline. It is widely used to treat patients presenting with back pain and fibromyalgia. Very rarely cyclobenzaprine toxicity can result in extrapyramidal symptoms, but occurrence of torticollis has not

The cyclobenzaprine structure is similar to amitriptyline; however, tricyclic antidepressant (TCA)-like wide complex dysrhythmia has not been reported. Our objective was to determine the incidence of TCA-like effects in cyclobenzaprine overdoses as reported to 6 poison centers for 2 years.
